Hazmat crews responded to a Mercer County water filtration plant Wednesday morning for a chlorine leak inside the facility.
The incident occurred around 5:45 a.m. in the Trenton Water Works plant located on Route 29 near the Calhoun Street Bridge, according to officials.
SkyForce10 was over the scene as firefighters suited up to enter the building.
There are no reported injuries.
Authorites said they are investigating the cause of the leak, which was placed under control by 6:45 a.m.
A similar hazmat incident occurred at this same facility on March 27. Crews responded after an alarm, set to sound when there is a chlorine leak in the building, went off. No one was hurt and there was no threat to the water supply.
